What are we humans basically made out of?
About 99 percent of your body is made up of
atoms of hydrogen, carbon, nitrogen and oxygen
. You also contain much smaller amounts of the other elements that are essential for life.
How are we made out of stardust?
When stars get to the end of their lives, they swell up and fall together again, throwing off their outer layers. If a star is heavy enough, it will explode in a supernova. So most of the material that we’re made of comes out
of dying stars, or stars that died in explosions
. And those stellar explosions continue.
What does it mean that we are made of stardust?
The outer layers collapse onto the core at nearly half the speed of light. The star then explodes outward as a supernova. This supernova explosion

How did humans come into existence?
The first human ancestors appeared between five million and seven million years ago, probably when

Are we made of light?
The
human body literally glows
, emitting a visible light in extremely small quantities at levels that rise and fall with the day, scientists reveal. … Past research has shown that the body emits visible light, 1,000 times less intense than the levels to which our naked eyes are sensitive.
Are humans made of energy?
all matter and psychological processes — thoughts, emotions, beliefs, and attitudes — are
composed of energy
. When applied to the human body, every atom, molecule, cell, tissue and body system is composed of energy that when superimposed on each other create what is known as the human energy field.
Are humans made of atoms?
About 99 percent of your body is made up
of atoms of hydrogen, carbon, nitrogen and oxygen. You also contain much smaller amounts of the other elements that are essential for life. … The very heavy elements in you were made in exploding stars. The size of an atom is governed by the average location of its electrons.

When was Adam and Eve born?
They used these variations to create a more reliable molecular clock and found that Adam lived
between 120,000 and 156,000 years ago
. A comparable analysis of the same men’s mtDNA sequences suggested that Eve lived between 99,000 and 148,000 years ago
